Probate/Will/Estate question about what was willed to me?

I live in Texas 4 years ago my parents died leaving property in a will. The will was probated and one year later was closed with 1/9 th ownership of the property between me and my 9 siblings. My question is, how can the property be being rented out without my permission and monies being collected on? Can only one sibling make that decision? And what can I do to stop it? And does the executor of the will have any more standing or decision making power now that the probate has been closed for over 4 years?
